To @ZZ whom t nto/,y concern:

Be it known that l, EDWARD FALES, of W'in.- throp, county of Suitolk, State ot Massachusetts,have invented an Improvement in Stoves or Furnaces, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its obj ect to im prove the construction of stoves, furnaces, or other heating apparatuses, whereby the smoke is chieiy consumed or freed from the heavy floating particles which tend to blacken it, thereby producing a White smoke, yet permit ting the use of bituminous or soft coal, and urhermore savinga large percentage of the In accordance with this invention vertical passages or fines are' formed upon the inside of the rear wall of the tire pot or chamber, or if said iire pot is made circular, said vertical passages may be formed upon more or less of the interior thereof, and a smoke consuming chamber is located above the lire pot having a series of small passages communicating with and forminga continuation of the vertical passages or fines in the lire pot. The vertical passages in the re pot serve as guide passages or iiues for the iiame and products of combustion, conducting them to the contracted passages in the smoke consuming chamber, and as the passages in said chamber are very small the entrances thereto will be lilled or choked with the flame, and the heavy particles of coal will be burned. To break up the continuity of the vertical passages in the tire pot and smoke consuming chamber, and thereby retard the progress of the iiame and the products of combustion, by turning them from a direct course, I have formed horizontal partitions in said guide passages just below the entrances to the passages in the smoke consuming chamber.

Figure 1, shows in front elevation a heating apparatus embodying this inventiomthe front wall being broken away to expose the part within; Fig. 2, a vertical section of the heating apparatus shown in Fig. 1, taken on the dotted line anw; Fig. 3, a top view of the heating apparatus shown in Fig. l, the top plates being removed or broken away to expose the parts beneath; Fig. 4,a modification showing a circular heating apparatus embodying this invention, and Fig. 5, a detail showing a dumping grate which may be used.

The grate` herein shown is iiat, and in Figs. l, to 3, is represented as substantially rectangular, comprising several parallel fingers or bars a,formed integral with or attached to the back or rear wall b, and above said Eingers or bars and extending for quite a dlistance parallel ribs c, are formed on said back or rear wall, the open spaces` between said ribs presenting unobstructed fiues or vents for the upward passage of currents of air and for guiding the iiame and products of combustion. The lower part of the ribbed portion of the said rear Wall b, serves as the rear wall of the fire pot or chamber containing the bed of coal. The rear wall b, extends below the grate a, and serves as the rear wall of the ash pit, which is provided with a suitable door (l, having a register or draft controller.

The fire pot or chamber containing the bed of coal has suitable side walls, a front wall, and a top Wall, the latter e, being connected to a suitable plate e', extending parallel to the rear wall b, and resting upon the ribs c, so that above and at one side of the top wall e, for a short distance, the lues or vents are closed on all sides to present a thin smoke consuming chamber having small passages or flues, communicating with or forming continuations of the guide passages of thetire pot. The vertical plate e', and rear wall b, are connected by narrow side walls, and atop e2, and as the 'ribs c, do not extend. but about half Way up said plate e', a narrow chamber is formed above the ribs to which the smoke pipesjf, are connected, said pipes terminating in a single pipe f2. Small horizontal partition Walls g, are or may be placed in the spaces between the ribs c, at a point a little below the entrance to thepassages of thesmoke consuming chamber, to direct the course of the currents of air or name or products of combustion, or break the straight continuous passages. The ribs c, terminate at the lower end at the grate a, the spaces between them communicating with the ash pit, and the door d, being provided with a suitable register permitting the entrance of a cur- IOO rent of air, the latter passes up through the said spaces between the ribs which serve as the nes or vents. These currents of air striking the partitions g, are diverted from their straight onward course andare directed into the chamber, after which they pass up through the small ilues or vents in the smoke consuming chamber, and then to the smoke pipes. If the partition walls g, are omitted the said currents of air will take a more direct course, but the result is substantially the same. In either case the White smoke is carried up free from the heavy foreign particles which tend to blacken it, said particles falling or being driven back on to the bed of coal to be consumed.

The top wall e, of the iire box is provided with suitable lids.

A rock shaft h, is :mounted in the sides of the ash pit beneath the lower ends of the ribs c, to which shaft a'series of fingers h, are -securedwhichare arranged opposite the spaces betweenzthe ribs, so .that when turned linto vertical position the lower ends of vthe iiues or vents will be closed. The hand lever h2, is pro-vided for turning -said shaft. This latter device is provided for retarding the combustion when desired, and when said lues or vents yare closed the currents of airwill pass up through the bed .of coal, but when said fines or vents are open the currents of air will kpass upxthrough them instead of 4through the bed of coal owing to the course being the one "of least resistance, although there will be a very slight draf-t up through the bed of coal.

On the rear side of the 'rear walll b, an .air chamber fi, is'form'ed which is open at the bottom and top to allow the vcold air near the floor to ascend, lthereby assisting in heating: the room, :as wellas creating a circulation of air therein, or as it is obvious the inlet may be "connected with. a cold air box or chute.

The grate g, instead of being formed int-egral with or secured to the rear Wall b, as. shown in Figs. 1, to 3, may be secured to a rock shaft as 4represen-ted in Fig. `5, in order that it may be dumped, orshaken.

Referring fto Fig. 4, the lire pot or chamber containing the bed of coal is made circular, and the Igrate bars g, may be forked if yde-` sired, and the ribs c, are arranged vertically on the rear Wall which in this instance is y made cylindrical, thereby presenting acentral air chamber within it, which has an inlet at 'thebottom and an youtlet yat the top. In vthis instance several doors d, will be provided, at different parts of the ash pit, and also several lids at different parts of the tire box.

It will be `seen that my invention is vsus-` ceptible of ymany modifications which comev Within the spiritand scope of my invention.

1t is obvious that the rear ribbed wall may be made in sections secured together and so also the other parts of the heating apparatus.

I claimv l. In a stove or other heating apparatus,a tire pot or chamber compri-sing a vertical front wall, side walls, and a rear wall, lthe latter having upon itsinside a series of parallel vertical ribs c, combined with the thin smoke consuming chamber rising from said fire pot, having a series of small flues or passages communicating with and forming continuations of the spaces between the ribs c, substantlally as described.

2. In a stove or other 'zheatingapparatus a fire :pot or chamber, the rear wall `of :which has ya series of vertical ribs yc,rto'present.guide passages or iiues yfor the flame fandproducts of combustion, combined `1with a thrnsmoke consuming chamber rising from .said i-re pot ydirectly above the guide passages lor fines formed in its rear side Wall, .and havingarseries .of small passages communicating with and forming continuations `:of saidguidezpas- -sages or dues, .substantially as described.

3. In la stoveor other heating apparatus, a 'fire pot or chamber, the rear'wall of twhich :has a seriesof `vertical ribsc, to ipresent guide `passages or tlues for the iiame andfprodzucts of combustion, combinedwith'the thin smoke consuming chamber or flue comprising the ribbed rear wall, which is a continuation of the `ribbed rear wall of the .tire potfandthe vertical plate upon 4the ribs of said rear-wall 1 yto thereby present passages communicating with and forming continuations of the guide passages in the tire pot, substantially as described..

4. In `a stove lor other heating apparatus, a tire pot or chamber, lthe rear Wallof 'which Vhas aseries of vertical ribs c,tozpresentiguide .passages or iiues for the flame and Yproducts of combustion, combined with the .thin smoke consuming chamber rising from Vsaid fire ypot directly above the guide passages oir fines formed in the rear sidewall, and having a series of small passages communicating with and vforming aloontinuation ofsaidguide passages or iiues, and horizontal partitions lolcated in said guide 'passages below the .entrances to lthe Iiues of the smoke consuming chamber, thereby breaking up their continuity, substantially as described.

In testimony whereof I have :signed vmy name to this specification in the presence of ltwo subscribing Witnesses.
